Film Camera Shutter Angle

Film Camera Shutter Angle. When you measure shutter angle, you are measuring the part of the rotary disc that is exposing the film to the light. The fastest shutter speed and narrowest angle on the blackmagic cinema camera is 45 degrees.

For a film shot at 24 fps, the standard shutter angle is 180 degrees. In this indietips.com video, i break down the basics of what shutter spee. The wider the shutter angle, from 270° up to 360° the more motion blur, and the narrower the shutter angle, (less than 180°), the less motion blur is perceived from one frame to the next.

But It's A Mild Pulse.


This is a 1/198 shutter speed, closest to 1/200 on a dslr. So lets say you needed to figure out what the shutter angle is for 1/50 of a second at 24 frames per second (fps). Paris, the great beauty of the cinema camera tradition of using shutter angle versus shutter speed is how you can so quickly visualize the resulting effect on motion in your frame compared to using shutter speeds.

360 Angle = 1/24 Speed (Not Possible With Film @24 Fps) 180 Angle = 1/48 Speed 144 Angle = 1/60 Speed 90 Angle = 1/96 Speed


For example, bell & howell eyemo 71k used a 160 degree shutter; The most common shutter angle used is 180 o, which gives us the ‘film look’ (remember, it’s not the most special, it’s simply the most common). If you have a wide shutter angle, anywhere from 270° to 360°, your shot will appear shaky, and will have greater motion blur.

To Find A Shutter Speed That Relates To A Known Shutter Angle, Do The Math In Reverse.


We always talk about shutter angles in terms of the portion of the disc which is absent. Download the complete blueprint to making a movie for free: This could be useful for creative purposes depending on the narrative or story you're trying to tell.

A Frame Rate Of 24 Fps With A Shutter Speed Of 1/48 Or 1/50 Will Give Your Footage A Smooth Cinematic Look And Feel.


Just double your frame rate. Javascript is disabled on your browser. This disk sits between the lens and the film, and rotates at a constant rate.

Shutter Angle Is The Term Used To Describe The Speed Relative To The Frame Rate.


At 24 fps the equation would be: It’s a rule that can be broken and played around with, but do be careful as although you’ll commonly get away with braking the rule it can at the worst possible times come back and get you. If the camera is taking a new picture 24 times a second, then the shutter is open for 1/48th of a second.
